        world_index: usize,
        error: TickError,
    },
    Observe(ObsError),
    Config(ConfigError),

    },
}

Error from a batched operation, annotated with the failing world index.

Variants

Step

A world’s step_sync() failed.

Fields

world_index: usize

Index of the world that failed (0-based).

error: TickError

The underlying tick error.

Observe(ObsError)

Observation extraction failed.

Config(ConfigError)

Configuration error during construction or reset.

InvalidIndex

World index out of bounds.

Fields

world_index: usize

The requested index.

num_worlds: usize

Total number of worlds.

NoObsPlan

No observation plan was compiled (called observe without obs_spec).

InvalidArgument

Batch-level argument validation failed.

Fields

reason: String

Human-readable description of what’s wrong.

Trait Implementations

impl Debug for BatchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for BatchError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for BatchError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for BatchError

fn eq(&self, other: &BatchError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
